WinSCP connect to Ubuntu. Access Denied

I installed Ubuntu13_desktop in VMware(VMware® Workstation 7.1.6) based with Windows 7. Now I want to connect to Ubuntu from Windows 7. Set the WMware as Host-only. Installed WinSCP in Windows, configured 

protocol: SFTP;
Host name: ubuntu;
Port: 22;
UserName: oracle;
Password: ***.

Clicked Login, it showed

Searching for host...
Connection to host...
Authenticating...
Using username "oracle"
Authenticating with pre-entered password.
Access denied.
Access denied.

I can succeed to ping Ubuntu by cmd.

Can anyone help me to let me access Ubuntu by WinSCP? Thanks in advance.

If sshd (openssh-server) is installed and running, but still no access when using WinSCP. In Ubuntu 16.x look at the auth logs:

sudo cat /var/log/auth.log

I found this:

No supported authentication methods available [preauth]

The problem is Ubuntu sshd configuration defaults to public/private key authentication for remote ssh access:

RSAAuthentication yes
PubkeyAuthentication yes
PasswordAuthentication no

If you want to skip the kay-pair work, Open the sshd conf file:

sudo nano /etc/ssh/sshd_config

Find the above attributes and modify to:

RSAAuthentication no
PubkeyAuthentication no
PasswordAuthentication yes

restart sshd:

sudo systemctl restart sshd

If you have set up a user on the Ubuntu 16.x instance, you now should be able to ssh or WinSCP with username/password. Please be aware that the security of the system is now at greater risk.

First look at auth.log on the system.

cat /var/log/auth.log

In my case with WinSCP, I found something like this:

fatal: no matching mac found: client hmac-sha1,hmac-sha1-96,hmac-md5 server hmac-sha2-512,hmac-sha2-256,hmac-ripemd160 [preauth]

And comment the line in /etc/ssh/sshd_config:

MACs hmac-sha2-512,hmac-sha2-256,hmac-ripemd160

don't forget to restart ssh :-) Hope this can help some one.

Well the port 22 is for SSH service. So you can probably try installing openssh-server in your ubuntu by typing

sudo apt-get install openssh-server

and then try connecting with the following details:

protocol: SSH

hostname: [IP Address of the computer]

port: 22

username: [username]

password: [password]

Hopefully this should work.
